Detailed Description
Fig. 1 is a schematic block diagram of a refrigerator 1 according to an embodiment of the present invention. The refrigerator 1 of the present embodiment should be understood in a broad sense, and may be, for example, a storage device having a low-temperature fresh-keeping function such as the refrigerator 1, a refrigerator, and a storage cabinet.
The refrigerator 1 may generally include a cabinet 10 and an oxygen treatment device 200.
The inside of the case 10 is formed with a storage space 100 for storing things and an installation space 101 located outside the storage space 100.
The storage space 100 of the present embodiment should be understood in a broad sense, and can be regarded as the storage space 100 as long as the storage space has the function of storing the articles to be preserved for the user. For example, the storage space 100 may refer to an inner space of a storage compartment, an inner space of a storage container disposed in the storage compartment, a peripheral environment space formed in the storage compartment and located outside the storage container, a receiving space of a bottle seat formed on a door body, and the like.
The installation space 101 may refer to a space other than the storage space 100, for example, an inherent space that may be provided for the refrigerator 1 to install other components (e.g., a compressor, an air duct, a foaming material, etc.).
The oxygen treatment device 200 is disposed in the installation space 101 and has an electrode assembly configured to treat oxygen of the storage space 100 through an electrochemical reaction, thereby increasing or decreasing the oxygen content of the storage space 100. The electrode assembly may generally include an anode 230 and a cathode 220, which perform oxidation and reduction reactions, respectively.
In the refrigerator 1 of the embodiment, since the storage space 100 for storing objects and the installation space 101 located outside the storage space 100 are formed in the case 10, the installation space 101 can be an inherent space of the refrigerator 1 for installing other components, the oxygen treatment device 200 is arranged in the installation space 101 located outside the storage space 100, the oxygen treatment device 200 does not occupy any position of the storage space 100, and the storage space 100 does not need to be subjected to space giving, so that the refrigerator 1 can realize air-conditioned fresh-keeping without affecting the volume ratio.
It should be emphasized that, for the air-conditioned fresh-keeping, in order to facilitate the oxygen treatment device 200 to adjust the oxygen content of the storage space 100, it will be easily understood by those skilled in the art that the provision of the oxygen treatment device 200 in the storage space 100, for example, on the storage container or on the inner wall of the storage compartment, will compress the volume ratio of the refrigerator 1 by adopting the principle of nearby. The inventor creatively sets the oxygen treatment device 200 in the installation space 101 outside the storage space 100 of the refrigerator 1, and utilizes the oxygen treatment device 200 to treat the oxygen in the storage space 100, which breaks through the concept of the prior art, provides a new idea for realizing the controlled atmosphere fresh-keeping of the refrigerator 1 under the condition of keeping a higher volume rate, and simultaneously solves a plurality of technical problems that the oxygen treatment device 200 is easy to be touched by users and the like.
In some alternative embodiments, storage space 100 is a low temperature region within tank 10. The installation space 101 is a high temperature region within the case 10, and its temperature is higher than that of the storage space 100. Where "high temperature" and "low temperature" are relatively speaking, the fact that the installation space 101 is a high temperature region does not mean that the temperature of the installation space 101 is necessarily higher than a certain temperature.
Since the storage space 100 for storing is a low temperature area in the case 10, and the installation space 101 is a high temperature area in the case 10, the temperature of the installation space is higher than that of the storage space 100, and the high temperature environment can increase the electrochemical reaction rate of the oxygen treatment device 200, the oxygen treatment device 200 of the refrigerator 1 can maintain high air conditioning efficiency, and meanwhile, the problem of freezing risk of the electrolyte is solved.
Fig. 2 is a schematic structural view of a refrigerator 1 according to an embodiment of the present invention.
In some alternative embodiments, a compressor compartment 160 for mounting a compressor is formed within the housing 10. The installation space 101 is formed in the press bin 160. The press bin 160 has a certain reserved space, and the space utilization rate of the refrigerator 1 can be improved by forming the installation space 101 using the reserved space and installing the oxygen treatment device 200. The oxygen treatment device 200 can exert high oxygen removal efficiency and oxygen production efficiency by means of the temperature environment of the press hopper 160.
In some alternative embodiments, at least a portion of oxygen treatment device 200 is contoured as curved surface 218 to fit within press cartridge 160. The press bin 160 is generally spherical in configuration. At least a portion of oxygen treatment device 200 is contoured as curved surface 218, and curved surface 218 may be matched to the spherical configuration of press cartridge 160.
That is, the embodiment further adjusts the outer shape of the oxygen treatment device 200 to fit the reserved space of the press house 160 on the basis of adjusting the installation position of the oxygen treatment device 200. In this way, the oxygen treatment device 200 can be smoothly placed in the installation space 101 in the press bin 160 without modifying the press bin 160 inherent to the refrigerator 1, which is advantageous in improving the versatility of the oxygen treatment device 200 and reducing the modification cost of the refrigerator 1.
Compared with the flat structure in the prior art, the oxygen treatment device 200 of the present embodiment adds the arc-shaped curved surface 218 structure, and creatively provides the novel oxygen treatment device 200 with unique shape and structure, which breaks through the idea of the refrigerator 1 adopting the flat structure for layout. The arcuate curved surface 218 structure not only perfectly matches the spherical structure of the press bin 160, but also increases the contact area of the oxygen treatment device 200 with the sphere. In this way, the oxygen treatment apparatus 200 can sufficiently contact the electrode assembly with the gas to be treated by virtue of the small volume. The oxygen treatment apparatus 200 has advantages of high air conditioning efficiency and miniaturization.
Cathode 220 is configured to consume oxygen of storage space 100 through an electrochemical reaction. Anode 230 is configured to provide reactants to cathode 220 through an electrochemical reaction.
Fig. 3 is a schematic structural view of an oxygen treatment device 200 of the refrigerator 1 according to one embodiment of the present invention.
In some alternative embodiments, oxygen treatment device 200 may include a housing 210 having an arcuate curved surface 218. The arc-shaped curved surface 218 is provided with a ventilation area 218a; the interior of housing 210 defines an electrolysis chamber 216 inside a gas permeable region 218a. Cathode 220 of electrode assembly is a plate of curved surface 218 that fits the shape of curved surface 218 and is disposed at gas permeable region 218a. Anode 230 of the electrode assembly is of opposite polarity to cathode 220 and is at least partially disposed within electrolyte chamber 216.
The ventilation areas 218a may be openings or through holes arranged in an array. Cathode 220 may be disposed inside breathable zone 218a and cover breathable zone 218a. Cathode 220 may have a waterproof breathable membrane. Alternatively, the breathable zone 218a is provided with a waterproof breathable film, and the cathode 220 is disposed inside or outside the waterproof breathable film.
For example, the housing 210 may have a hollow sphere shape with a wall that forms an arcuate curved surface 218. The ventilation area 218a is disposed on a hemispherical surface of the housing 210. Anode 230 is opposite cathode 220 and is disposed within a central cut-away surface of housing 210.
As another example, the housing 210 may be hollow and cylindrical with its walls forming an arcuate curved surface 218. The air permeable region 218a is disposed on a half side of the housing 210. The half side of the case 210 refers to half of the side of the cylindrical case 210 taken along the central longitudinal section of the cylindrical case 210. Cathode 220 is disposed at gas permeable region 218a and anode 230 may be disposed within a central longitudinal cross-section of cylindrical housing 210. For example, the plate surface of the anode 230 may have a rectangular parallelepiped shape having a width equal to the diameter of the cylindrical case 210 and a length equal to the height of the cylindrical case 210 so as to be disposed right at the central longitudinal cut surface of the case 210, thereby obtaining the maximum plate surface area.
Fig. 4 is a schematic structural view of a refrigerator 1 according to another embodiment of the present invention. Fig. 5 is a partial enlarged view at a in fig. 4.
In some alternative embodiments, a foam layer 180 for thermal insulation is also formed within the housing 10. The inside of the case 10 is the entire space inside the outer peripheral wall of the refrigerator 1. The foaming layer 180 is located inside the case 10. The installation space 101 is formed in the foaming layer 180. The foaming layer 180 may form a cavity by a molding process, the shape of which is adapted to the shape of the oxygen treatment device 200, such that the oxygen treatment device 200 is adapted to fit into the cavity.
The mounting space 101 for mounting the oxygen treatment device 200 is formed in the foaming layer 180 by adopting a forming process, so that the subsequent working procedures such as punching or punching can be omitted, the process consistency can be ensured, the processing precision of the cavity can be improved, the oxygen treatment device 200 can be well assembled in the cavity, and the damage rate can be reduced.
The shape of the cavity may be set according to the shape of the oxygen treatment device 200. In some alternative embodiments, for example, when the installation space 101 is formed in the foaming layer 180, the oxygen treatment device 200 may have a flat shape, such as a flat rectangular parallelepiped shape. The oxygen treatment device 200 of this shape may have a small thickness in a certain direction so as to be accommodated by the foaming layer 180 having a limited thickness.
In some alternative embodiments, the housing 20 includes an inner bladder. The inner side of the inner container defines a storage space 100. The installation space 101 is formed at a side of the inner container facing away from the storage space 100, i.e., at a rear side of the inner container, which can shorten a distance between the oxygen treatment device 200 and the storage space, simplify a structure of the air path assembly, and reduce manufacturing costs.
For example, the housing 210 of the oxygen treatment device 200 may have a substantially flat rectangular parallelepiped shape. And the housing 210 is provided with a lateral opening. Cathode 220 is disposed at the lateral opening to define, with housing 210, an electrolyte chamber 216 for containing an electrolyte. Anode 230 may then be disposed within electrolysis chamber 216.
In some alternative embodiments, refrigerator 1 may further include an active circulation circuit coupled between storage space 100 and oxygen treatment device 200 configured to facilitate circulation of air flowing from storage space 100 to oxygen treatment device 200 and then back to storage space 100. In this embodiment, the storage space 100 may refer to the low oxygen storage space 120. The low oxygen storage space 120 may have an air outlet 122 and an air return 124 for exhausting and receiving the gas, respectively.
Because the active circulation gas circuit is connected between the storage space 100 and the oxygen treatment device 200, under the action of the active circulation gas circuit, an air flow circulation channel can be formed between the storage space 100 and the oxygen treatment device 200, which is beneficial to improving the air flow circularity of the air conditioning process, improving the air flow circularity of the air conditioning process and further optimizing the air conditioning efficiency.
Under the action of the active circulation gas path, the gas to be treated in the storage space 100 can smoothly flow to the oxygen treatment device 200, and oxygen in the gas to be treated is used as a reactant to participate in the electrochemical reaction of the cathode 220, so that the oxygen content in the gas is reduced, the low-oxygen gas can return to the storage space 100, and the storage space 100 can form a low-oxygen fresh-keeping atmosphere after one or more airflow circulation.
With the above structure, the gas flow to be treated can be orderly guided to the cathode 220, and the oxygen in the gas flow participates in the electrochemical reaction at the cathode 220, so that the oxygen is consumed, thereby forming a low-oxygen treatment gas flow, which can be orderly guided to the storage space 100, the order of the whole gas flow treatment process is strong, and the gas flow treatment efficiency is improved.
In some alternative embodiments, oxygen treatment device 200 further includes a process tunnel 214c, process tunnel 214c in gas flow communication with the active circulation gas path for flowing gas from storage space 100 through cathode 220. That is, the process air duct 214c of the present embodiment serves as a guide, and the gas from the storage space 100 flows through the cathode 220 under the guide of the process air duct 214c.
In the refrigerator 1 of the embodiment, the processing air duct 214c can enable the gas from the storage space 100 to flow through the cathode 220, so that the cathode 220 can process the oxygen in the gas, so that when the gas environment of the storage space 100 needs to be regulated, only the active circulation air path needs to be communicated with the processing channel, the whole oxygen processing device 200 does not need to be arranged at the ventilation area 218a of the storage space 100, and the oxygen processing device 200 can be arranged at other positions far away from the storage space 100.
The flow path of the gas to be treated in the oxygen treatment device 200 forms a treatment tunnel 214c. Since the process air duct 214c allows the gas from the storage space 100 to flow through the cathode 220, the process air duct 214c can sufficiently contact the gas with the cathode 220 in the process of guiding the gas, and the refrigerator 1 can obtain higher air conditioning efficiency based on the guiding effect of the process air duct 214c.
In some alternative embodiments, the active circulation path includes an intake fitting 310 and a return fitting 320.
Wherein the air inlet pipe 310 communicates the air inlet end of the processing air channel 214c with the storage space 100, and is configured to convey the air flow from the storage space 100 to the processing air channel 214c. The air return pipe 320 communicates the air outlet end of the processing air channel 214c with the storage space 100, and is configured to convey the air flow processed by the cathode 220 to the storage space 100. Wherein, the air outlet 122 of the low oxygen storage space 120 may be connected to the air inlet pipe 310, and the air return port 124 is connected to the air return pipe 320.
Since the gas to be treated flows to the treatment air duct 214c through the air inlet pipe fitting 310, and the gas flow after being treated returns to the storage space 100 through the air return pipe fitting 320, the air inlet pipe fitting 310 and the air return pipe fitting 320 are separately and independently arranged, and the air flow to be treated and the air flow after being treated are not obviously mixed, so that the air flow after being treated is reduced or prevented from being mixed into the air flow to be treated, and the air conditioning efficiency is ensured.
In some further embodiments, an airflow actuation device 330 is disposed on the active circulation path and is disposed in the airflow path of the intake tube 310 and configured to cause airflow circulation. Under the action of the airflow actuating device 330, the airflow flowing rate in the airflow circulation channel can be increased, so that the airflow to be treated in the storage space 100 flows to the treatment air duct 214c in a 'sequential' manner, thereby improving the air conditioning efficiency. For example, the airflow actuation device 330 may be coupled to the airflow inlet of the intake fitting 310.
For example, the air outlet end of the airflow actuating device 330 may be connected to the air inlet end of the air inlet pipe 310, and the air inlet end of the airflow actuating device 330 may be connected to the low oxygen storage space 120, which is beneficial to improving the airflow actuating effect, thereby accelerating the airflow circulation rate.
In some embodiments, the airflow actuating device 330 may be an axial fan or a centrifugal fan, but is not limited thereto, as long as it can function to guide the directional flow of the airflow.
In some alternative embodiments, the housing 210 of the oxygen treatment device 200 may have an airflow chamber 214214 and an electrolysis chamber. The gas flow chamber 214 communicates with the electrolysis chamber through an opening to which a cathode 220 is fitted to space the gas flow chamber 214 from the electrolysis chamber. That is, cathode 220 isolates airflow chamber 214 from the electrolysis chamber by closing the opening. The opening may be provided in a longitudinal cut-out of the housing 210. The area of the opening may be less than or equal to the cross-sectional area of the longitudinal cross-section.
In this embodiment, the airflow chamber 214 and the electrolysis chamber may be formed as a single piece, for example, by a molding process, which may simplify the processing of the housing 210. In some alternative embodiments, airflow chamber 214 may not be integral with the electrolysis chamber. For example, the electrolysis chamber may be generally in the shape of a flat cuboid with its wider sides having mounting openings to which cathodes 220 are fitted to close the electrolysis chamber. The airflow chamber 214 may be generally flat, rectangular parallelepiped with open sides and cover the wider sides of the electrolysis chamber.
The interior of the electrolysis chamber forms an electrolysis chamber 216. The interior of airflow chamber 214 may form a process tunnel 214c. The airflow chamber 214 is provided with an inlet 214a and an outlet 214b, wherein the inlet 214a is in communication with an inlet pipe 310 and the outlet 214b is in communication with an outlet pipe 320.
Of course, the above examples of the external shape of the oxygen treatment device 200 are exemplary, and the external shape of the oxygen treatment device 200 is not limited thereto. In other embodiments, the oxygen treatment device 200 may be transformed into other shapes, such as polyhedral shapes, as desired.
Fig. 6 is a schematic structural view of an oxygen treatment device 200 of a refrigerator 1 according to another embodiment of the present invention.
In some alternative embodiments, cathode 220 and anode 230 each comprise a plurality of segments of electrode plates and each collectively enclose a hollow cylinder, such as a hollow cylinder, or a hollow prism, or the like. The hollow prism may be a triangular prism, a quadrangular prism, a pentagonal prism, a hexagonal prism, or the like, and is preferably a quadrangular prism.
The hollow cylinder in which cathode 220 is located is nested inside the hollow cylinder in which anode 230 is located. An electrolysis chamber 216 is formed between cathode 220 and anode 230. The side of cathode 220 facing away from anode 230 forms a process tunnel 214c in gas flow communication with storage space 100 such that oxygen in the gas flowing through process tunnel 214c contacts cathode 220.
In this embodiment, the processing tunnel 214c has a definite air inlet end and air outlet end, and extends from the air inlet end to the air outlet end. The gas to be treated can flow along the extending direction of the treatment air duct 214c, and oxygen in the gas continuously participates in electrochemical reaction and is consumed in the flowing process, so that the gas flowing out of the treatment air duct 214c contains little oxygen, which is beneficial to strengthening the air conditioning effect, reducing the time required by air conditioning and reducing the circulation times of air flow. Only one or a small number of gas flow cycles may be required between the storage space 100 and the oxygen treatment device 200 to meet the oxygen reduction requirement of the first storage space 100.
In some alternative embodiments, oxygen treatment device 200 further includes a first bezel 250 and a second bezel 260. The first protection frame 250 is in a hollow column shape and is sleeved outside the hollow column where the anode 230 is located. The second protective frame 260 is also hollow and is sleeved inside or outside the hollow column where the cathode 220 is located. And the first and second sheathing frames 250 and 260 close the gap between the anode 230 and the cathode 220.
The first and second protective frames 250 and 260 are used to protect the anode 230 and the cathode 220, respectively, which may improve the structural strength of the oxygen treatment device 200 to some extent, and reduce or avoid leakage of electrolyte.
For the electrochemical reaction of cathode 220 and anode 230, for example, oxygen in the air may undergo a reduction reaction at cathode 220, namely: o (O) 2 +2H 2 O+4e - →4OH - . OH generated by cathode 220 - An oxidation reaction may occur at the anode 230 and oxygen may be generated, namely: 4OH - →O 2 +2H 2 O+4e - . Anode 230 is utilizing OH - The electrochemical reaction takes place and the reaction proceeds to the cathode 220 provides a reactant, e.g. electron e - . Anode 230 also generates oxygen when undergoing an electrochemical reaction.
In this embodiment, the storage space 100 may include a low oxygen storage space 120 and a high oxygen storage space 140. Since the anode 230 generates oxygen when performing electrochemical reaction, the oxygen can be utilized, for example, the oxygen can be delivered to the high oxygen storage space 140 of the refrigerator 1, which can improve the air conditioning capability of the refrigerator 1 and create a low oxygen fresh-keeping atmosphere and a high oxygen fresh-keeping atmosphere at the same time. For example, an oxygen delivery line may be in communication between the electrolysis chamber 216 and the high oxygen storage space 140. The oxygen treatment apparatus 200 may have an exhaust port 21 for exhausting the separated oxygen. The first end 420 of the oxygen delivery line 400 may be in communication with the exhaust port 21 of the oxygen treatment device 200 and the second end 440 may be in communication with the high oxygen storage space 140, thereby directing the oxygen discharged from the exhaust port 21 to the high oxygen storage space 140.
